Summary: I had to get a new mouse for work. We don't have a budget so I had to get something cheap. I'm angry at the guy at the store who sold this to me. It's super loud, is clumsy and not clean in its functions, and now I'm stuck with it! Arrgh!
Summary: I've used Logitec optical wireless mouses, but keep losing the USB connector. This model -- MSFT 4000 -- was on sale at a local office supply store for almost half the Logitec model I usually buy. Plus it said '1000 dpi for precise cursor control'. So far, the cursor is unwieldy at best, and the design of the mouse itself is atrocious. The top, for fingers, etc., must have been designed for robotic hands that are of equal length, width, and pressure sensitivity.
Summary: We bought this mouse about 3 years ago, Cons: Somtimes it starts to randomly move across the page. Randomly JERKS EVERYWHERE IN RANDOM DIRECTS. (Video Game hazard) Somtimes it does this in a manner when you click, so then it gos up too the X on a fullscreen program so fast that you acidently click out of it. this has happened to me several times .....
Summary: Microsoft Notebook Optical Mouse 4000--Dark Gray (B2P-00006) - mouse. This is the worst wireless mouse I have ever used. Very cheaply made, poor design all around. Battery compartment is flimsy and very hard to close/keep closed. In attempting to retrieve the reciever I accidently ejected the entire thing. Magnifier button placing is awkward and too easily triggered with simple use. I immediately asked for a refund.
